2005 Buick Rainier

The subject vehicles are model year (MY) 2002-2009 Chevrolet Trailblazer, GMC Envoy, 2004-2007 Buick Rainier, 2003-2008 Isuzu Ascender, 2005-2009 Saab 9-7X, 2002-2004 Oldsmobile Bravada, 2003-2006 Chevrolet SSR, 2005-2009 Buick Lacrosse, and 2006-2008 Pontiac Grand Prix. This scope includes the Trailblazer/Envoy variants: 2002-2006 Envoy XL/Trailblazer EXT and 2004-2005 Envoy XUV. The original scope of this investigation was expanded to include all vehicles equipped with the subject Headlight Driver Module (HDM). The focus of the investigation was to determine whether actions performed by General Motors adequately addressed any unreasonable risk to motor vehicle safety in the subject vehicles concerning the headlights and the HDM that controls them.Under normal electrical load and environmental conditions, the HDM can overheat inside the Underhood Electrical Center (UEC). This can cause the module to fail and result in a simultaneous loss of both low beam headlights and both daytime running lights (DRLs), often with no warning or prior detectability to the driver. This failure can be intermittent or permanent. No other exterior lights are affected. High beams, turn signals, brake lights, and reverse lights are still operational.General Motors addressed this issue with 2 recalls (14V755 & 15V519) and a special coverage program (N172091910). In view of the recalls and special coverage program implemented by GM and the vehicle high beams continuing to operate, ODI has tentatively concluded that the actions taken by GM mitigate any unreasonable risk to safety posed by HDM failure in the subject vehicles.Accordingly, the investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.The ODI reports cited above are available for review online at NHTSA.gov under the identification numbers in the attached document.

The office of defects investigations (ODI) analyzed complaint data provided by General Motors (GM) as well as complaints submitted to ODI from consumers.In total, there were 5,089 unique reports indicating an inaccurate fuel level reading while driving.General Motors stated that this condition occurs when the contacts of the fuel sensor wear prematurely.Most of the complaints indicated an empty fuel gauge reading after filling the tank.Less than 10 percent of theODI complaints involved an engine stall incident.During this investigation, GM developed a remedy procedure and issued special coverage bulletin instructing dealers to install a new design fuel level sensor.The bulletin was sent to dealers on August 10, 2011 and the owner letter mailing began on August 15, 2011.See the investigative file for copies of GM's bulletin and owner letter.This preliminary evaluation is closed.

The Office of Defects Investigation has received 668 complaints alleging inaccurate fuel gauge reading while driving in model year 2005-07 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, and Saab 9-7x vehicles.Of the 668 complaints, 58 incidents were alleged to result in a vehicle stall.Of the 58 stalling incidents, 43 complaints reported stalling because the fuel level reading indicated more fuel availability than what is actually in the fuel tank. One complaint alleged a vehicle crash after the vehicle stalled while exiting the interstate, became disabled, and was struck from behind.Summarily, the complaints show an apparent increasing trend, with most complaints received within the past year.A Preliminary Evaluation has been opened to assess the scope, frequency and potential safety consequences associated with the alleged defect.

My 16 year old son was making a left hand turn out of a school onto a road with no curve, no hole, no accident but the 4 side air bags deployed for no reason. He was OK and pulled over for safety and got a ride home. We had it towed home and contacted gmac buick and they had it towed to a dealership and had a diagnostic test ran and found no reason for them to deploy but they said the car had been altered because we had put subs and a radio in it through a lisc. Professional but that makes them not liable for anything that would happen. They said putting a radio in can cause the bags to deploy or brakes to fail and it is in their manual and they are not liable for any problem if we alter the car in any way. If this is the case anyone with an aftermarket radio should be warned that their child car anyone can be killed and it will. E no one's fault. I am out a car because insurance said they don't cover it because it wasn't an accident and GMAC says it happens not uncommonly but that they will not help in any way. They told me I was not allowed to talk abijt this to anyone. They read me a statement on the phone which said I can not talk outside of GMAC. They don't want people knowing this is happening. People need to be aware that bags can randomly deploy and if he was in the interstate he could have been killed. I am terrified to get in it and drive. Why do people not know this can happen. Why is gmac not doing anything or putting out psas saying people could die if they out sibs in professionally or otherwise.

WHILE DRIVING DOWN THE INTERSTATE LAST NIGHT AT ABOUT 70 MPH MY LOW-BEAM HEADLIGHTS SUDDENLY WENT OFF PLUNGING THE ROAD AHEAD OF ME INTO PITCH BLACK DARKNESS. FULL BEAM AND DIRECTIONAL LIGHTS WERE STILL FUNCTIONING, MANAGED TO SAFELY PULL OF TO THE SIDE OF THE INTERSTATE, AND LUCKILY WAS ABLE TO USE MY CELL PHONE TO DETERMINE THAT THE SOLID STATE HEADLIGHT RELAY HAD FAILED. LUCKILY THERE IS A SIMILAR RELAY LOCATED IN THE FUSE BOX THAT CONTROLS THE ENGINE FAN THAT I WAS ABLE TO UTILIZE AND CONTINUE ON MY JOURNEY. NEEDLESS TO SAY THIS WAS A VERY UNNERVING/SCARY EXPERIENCE AND CAN'T IMAGINE WHAT IT WOULD BE LIKE FOR A LESS EXPERIENCED DRIVER. I FIND IT HARD TO BELIEVE THAT GM THOUGHT THAT A SYSTEM THAT COULD AFFECT BOTH HEADLIGHT SIMULTANEOUSLY IN THIS WAY WAS REMOTELY EVEN A GOOD IDEA?!
